Usage Tips:1. Automatic transfer switch can switch between normal power and reserve power automatically. This switch prioritizes normal power. If normal power is available, the switch will connect to normal power. If normal power is off and reserve power is on, the switch will transfer to reserve power. Note: The switch does not start or stop the generator. 2. Operation: - Set the switch to Automatic mode: the transfer between normal and reserve power occurs automatically. - Set the switch to Manual mode: the transfer must be performed manually. 3. The Automatic Transfer Switch is a terminal-type automatic transfer device designed for use in 3-phase 4-wire (or 1-phase 2-wire) AC 50/60Hz systems, with a rated voltage of 230V and maximum current of 63A. It monitors Phase A voltage from both normal and reserve power sources. In case of loss of voltage or phase failure, it automatically transfers the load circuit from the failed source to the active source to maintain power supply. Rated voltage: AC 230V 50/60Hz Note: Power interruption may occur during switching. Maximum current: 63A Color: Grey + Black + Blue Material: PC plastic Package Contents: 1 x Automatic Transfer Switch Note: Light and display settings may cause slight variations in color appearance. Measurement may vary by +/- 1-3 cm.
